Information

DETAILS:

REPLACE:
To ensure zero gap in your 2-way humidity control, replace your Boveda every 3 months. Order replacement packs BEFORE Boveda is rigid all the way through to avoid a lapse in humidity protection in your cannabis container. 
Boveda is still working if you feel:
  • Hardening at its corners
  • Soft spots among some hard areas

Boveda is expired if:
  • The entire pack feels rock solid all the way through

HOW TO USE:

Boveda is safe to touch cannabis.
First, remove a Boveda pack from the resealable bag, making sure to reseal the bag afterward. Then simply place the pack in your cannabis container. Seal your container closed to ensure it's airtight. That's it!
Do not mix Boveda RH levels within the same container, and do not use Boveda in the same container with other humidification products. They will counteract each other and reduce the efficiency of the Boveda.

INGREDIENTS:

Food-grade salt, purified water, and a food-grade thickening agent.

    Don’t wait to get this product

    I bought the 58% pack and I am truly impressed, with the humidity only fluctuating 1-2 percent depending on how much I put in my jars. The biggest issue I have is WHY I didn’t buy this product sooner and I am so impressed that I signed up for the automatic purchase and can’t see myself Ever doing without. After all your hard work, do not go without using using these packets, you will be glad you did
